Problem: Service Configuration Error Messages (Service Configuration Error Messages)

Sometimes, during boot-up of a Cisco device through Cisco IOS software, error messages similar to these are displayed.

%Error opening tftp://255.255.255.255/network-confg (Socket error)

%Error opening tftp://255.255.255.255/cisconet.cfg (Socket error)

%Error opening tftp://255.255.255.255/3620-confg (Socket error)

%Error opening tftp://255.255.255.255/3620.cfg (Socket error)

Actual example.

%SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp://255.255.255.255/cisconet.cfg) failed

These error messages are related to the default service configuration option built into the Cisco IOS software, which attempts to access the service configuration file from a (TFTP) server.

To view the configuration.

Enter the show run command

———————–

Router#show run
Building configuration…

Current configuration : 7722 bytes
!
version 15.4
service config
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption

……

———————–

Solution.

To turn off this feature, enter the command no service config globally on the router

Router#config terminal
Enter configuration commands, one per line.  

Router(config)#no service config

Router(config)#exit

Router#copy running-config startup-config

Which error messages will no longer appear after the next restart of the router
